Hi
I have just acquired a merc e class with a comand APS centre with sat nav. I can put destinations in it but as soon as I ask it to give directions it brings France up where it thinks we are and calculates our journey from there when I'm in Cornwall! GP is on or so it says but after an hour and a half driving it still had not updated my current position.Any ideas please?
